BABYS CHAIR.

SPECIFICATION forming part of Letters Patent No. 451,058, dated April28, 1891.

Application filed June 12, 1890.

To all whom it may concern:

Be it known that I, CARL D. KOESER, a citizen of the United States,residing at the city of Oshkosh, in the county of Winnebago and State ofWisconsin, have invented certain new and useful Improvements in BabiesChairs; and I do declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to that class of childrens chairs provided withtrays and to the manner of attaching the tray; and the objects ofmyinvention are to simplify, cheapen, and render more durable and securethe manner of fastening the tray. It is advisable in chairs of thisdescription to so attach the tray that when it is swung around from thefront of the chair it will drop down and hang at the side, and for thispurpose a universal or ball-and-socket joint has heretofore been provided to attach the tray to the arm. Such a joint is necessarilycomplicated and expensive, and when broken practically incapable ofbeing repaired. Also, in the manner of latching the tray at the otherend when swung before the child several devices have heretofore beenused, but have been so located and constructed that the child soonlearned to open them and obtain release from the chair.

In the accompanying drawings, Figure 1 is a bottom View of the chair andtray; Fig. 2, a side Viewshowing the tray down; and Figs. 3 and 4,detail views of the hinge and latch, respectively.

A is the seat, and G G the arms to which the tray F is attached.

, To attach the tray, the end of the arm G is simply tenoned into thering aand the detaining-cap 1) attached by means of the screw 1)screwing into the end of the arm, so as to allow the ring to turn aroundupon the arm. The plate f, which is integralwith the ring a,

' attaches to the bottom of the tray by means of the screw orbolt c,which turns in an openfierial No. 355,132. (No model.)

ing a in the plate f, so as to allow the tray to be turned horizontallybefore or away from the child. When the tray is swung clear around totheside, it drops down, the ring a turning upon the tenon a, Fig. 3.

e is a latch attached to the bottom of the tray by the screws 2' 1' t,and d is a corresponding catch on the arm G, fitting therein when thetray is closed. I construct and locate this latch beneath the tray withthe thumb-piece toward the center and away from the edges .of the tray,so that the child when sitting in the chair cannot reach it either fromthe front or side for the purpose of unlatching it, and yet it iseasilyaccessible to a person standing in front.

The latch consists of the cover n, Fig. 4., the thumb-piece a, notchedat e to engage the corresponding catch d upon the arm G and pivoted att. A downward pressure at e raises the notch e to release the catch 01,it being tapered at the end, so as to latch automatically. Thespringwserves to raise the thumbpiece e and prevent rattling of thelatch.

By means of my invention I secure the arm at the end when latched,thereby preventing the arms from spreading apart, as they do whenlatched at the side.

The catch cl is secured, as shown, in the end of the arm G, so that whenthe tray is swung around the shoulder surrounding the catch 30 forms afixedstop for the tray at the proper locking-point. The pivotal supportfor the thumb-piece on the latch also acts as a stop by striking the endof the catch d. The tray is thus not only securely latched, but isprevented from working loose in either direction.

I provide a simple and durable means of' locking the tray, so that achild in the chair cannot unlock it.

Difierent forms of the same appliances may 9 be used to adapt myinvention to rounded or circular arms. Therefore What I claim as myinvention, and desire to secure by Letters Patent, is-

1. A childs chair provided with a shoul-= dered arm a, a tubular socketa, turning on said arm, said socket being provided with a plate f,integral therewith, a screw I), provided for arresting the latch at aposition of engagement with the catch, and a spring to normaliy lock thesame, substantially as shown.

in testimony whereof Iaffix my signatnrein presence of two witnesses.
